gpio: Add driver for Zynq GPIO controller
Add support for GPIO controller used by Xilinx Zynq.
v3 changes:
- Use linux/gpio/driver.h instead of linux/gpio.h
- Make irq a local variable in probe
v2 changes:
- convert to pm_runtime_force_(suspend|resume)
- add pm_runtime_set_active in probe()
- also (un)prepare clocks when they are dis-/enabled
- add some missing calls to pm_runtime_get()
- use pm_runtime_put() instead of sync variant
- remove gpio chip in driver remove()
- remove redundant type casts
- directly use IO helpers
- use BIT macro to set/clear bits
- migrate to GPIOLIB_IRQCHIP
